[Mindfulness.]

Hello!
I completely agree with Dez.
It can be hard to focus on the positive attributes and qualities that we have and when we don't have self-confidence, this can often be obvious to those around us. When you come more confident, it can reflected on how we act. I understand this is better said than done but a good activity to engage in is writing down all the things you are good at as well as what you love about yourself and read it daily (if you have time).
Is there someone that you can talk to that will help you with your thoughts such as a psychologist? I can imagine that these negative thoughts you have about yourself isn't easy to deal with.
Take care of yourself and please remember that the right person will come along for you.
